i have a very basic question, but i found no answer. i just installed the effect "greenbox". really good stuff.

but, how can i use, add more than one effect to a videolayer. i search for the possibility, to change the brightness of a video. is this possible? or
is it basicly possible to use more than one effect on a layer? hope you understand what i mean.
thank you for your support.

If the picture is static I advise you to use Photoshop or another paint application to turn it into a transparent picture. BluffTitler can import transparent PNG, BMP and TGA files.

Only for videos and realtime video captures (like webcams) using an effect like this GreenScreen.FX makes sense. If you want I can make a bluescreen or a redscreen variant for you, but grey is a bad choice for the colour key.

I understand what you say about green, and it's fine to use a green screen background if you have production control of the shooting location ... but ... if a friend wants to just shoot some video of himself ... he's just average Jo Public who doesn't have access to green screen backdrops ... so you just have to make do with whatever colour wall is behind him.

I have copied the GreenScree.fx and Chromkey.fx file in the effect folder under media file. But when I browse from BT windows I can't find them there.

For example, I inserted video capture layer and make it as active layer (made the background of my video capture layer green using green wall behind). Then I want to change effect of this active layer to impose the effect of chromakey or Green-Screen effect to have a transparent video capture.

Then I click the change effect from the tool window to browse and select the GreenScreen.fx or Chromakey.fx but unfortunately I do not see the effect files there and only see the pre-existing effects. However, If I browse to the folder through explorer I can see both GreenScreen.fx or Chromakey.fx files along with all other pre-existing effects.

Dear Rahul,
1. simply press F9 there you will select the "select effect" then a dialog box will appear
that is Effects folder of bt... there you select picture folder there you will find both GreenScreen.cfx or Chromakey.cfx ... you can apply them in your desired pic or video.
C:\Outerspace Software\BluffTitler\Media\Effects\Picture..
you are saying "GreenScreen.fx or Chromakey.fx but they are old effects they are now .cfx not .fx .
Note: kindly check your bt version.... you can download latest version from the below link .. current version is BluffTitler 13.4.

simply check this show for Green screen show... this comes with installer shows...

Hello Dani
Thanks for your suggestions. I have been through this lesson that you mentioned, which just work like bullet. Can you suggest me if we can use the effect in the video capture effect, while capturing video with a green background? Please use the following two options in your computer and let me know the result. This might give you a sense of the problem I am facing.

I am using BT-13.4 (Pro) and I tried two ways-

(i) adding video capture layer (green screen behind) and using this effect. This is like a live video on an existing template. Result: failed!
(ii) inserted pre-captured video layer (with green background) in an existing template and use this effect. Result: failed

I have attached a sample video file that I have tried, you can use this one if you want.
